Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered other phenolic carboxylic acid
Not specifically 'hydroxycinnamic' per description, so residual other phenolic acids in same heading.
If used primarily as synthetic fluorescent brightener
Chapter excludes synthetic organic products used as luminophores/brighteners (3204), shifting from pure chemical.
If esterified with sugar or as salt of vitamin
Sugar esters/salts of Chapter 29 acids classify under 2936 per Chapter note (c), later numerical order.

Import Tips & Compliance
• Include FTIR or HPLC certificate verifying ≥99% purity and CAS 537-98-4 to distinguish from esters or derivatives
• Label as 'food grade' or 'cosmetic grade' with heavy metal limits (<10ppm) per FDA import requirements
• Avoid retail packaging (>20kg drums preferred) to prevent classification as Chapter 32 coloring matter preparations
